As soon as I opened the box my 90cu tank came in I was impressed. Very light weight but you can still tell it was well built. No chrome or polished parts on the outside. Also came with a nice cap and extra O-ring. Before my first game I sat down and adjusted the output pressure from the stock 800 psi to 600. That process was really easy. Fit perfectly in my spec ops vest. After playing with it, I made everybody jealous. Went a whole day of playing and only used about half my tank. Best part was my buddy just bought a 68/4500 tank from the local shop for the same price as my 90cu.

Conclusion:

My final opinion- GET ONE! Its one of the best investments I ever made.
